You know what's happening right? At 7pm in each country around the world you'll be able to hear the new Sigur Ros album Valtari for one-hour-only. This hour will be known forevermore as the Valtari Hour.

DiS is one of the official UK partners streaming the album in its entirety, so bookmark this page or leave it open in a tab, and wander back here to listen to the record later (or now, if it is 7pm UK Time when you load up this page). Obviously, if you're a time traveller and have been forward to 7pm tonight, please comment below telling us what we can expect...
